It accepts a crystal input and delivers up to fifteen clock outputs from a single reference — the 1:15 ratio means one crystal drives the whole clock tree without external fanout buffers. Maximum output frequency is 66.66 MHz, placing it in the range for legacy x86 chipset or embedded controller clocking. ## Package and temperature grade The differential input and output are both marked No — all clocks are single-ended, which simplifies PCB routing but limits noise immunity on long traces compared to a differential LVDS or HCSL output.","metaTitle":"Infineon CY2254ASC-1 Clock Synthesizer, 66.66MHz, 28-SOIC","metaDescription":"Infineon CY2254ASC-1 processor-specific clock generator, PLL-based, 66.66MHz max, 1:15 fanout, 28-SOIC.
